7 Application filed July 25 1901. Serial No. 69,634. (No model.)

To all whmn it may concern:

Be it known that I, FINLAY R. MCQUEEN, a citizen of the United States, residing at Superior, in the county of,Douglas and State of IVisconsin, have invented certain new'and' consists of the novel devices and combina tions of devices hereinafter described, and defined in the claims.

From a broad point of view my invention consists in winding wire between the tileblocks, bricks,or other block material of a wall and embedding the samein the mortar or cement which is used to join the said blocks or bricks. especially directed to the improvement of cylindrical bins wherein the walls are built up of hollow tile-blocks. In this application of my invention the binding or reinforcingv wires are wound spirally and in horizontal planes at suitable intervals between the tileblocks and are thus made to afford racks or skeleton supports which are adapted to support the cement or mortar while in plastic condition. After the mortar or cement becomes hardened or set, so as to rigidly unite the tile-blocks, the embedded wires serve to reinforce the walls and to adapt them to with stand the lateral strain due to the internal pressure of the contents of the bin.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

dispense.

My invention is, however,

wound or interposed between the layers of tile-blocks, the thicknessof the wall being greatly exaggerated; and Figs. 4 and 5 are perspective views showing portions of a binwall built of brick and also embodying my invention.

In Figs. 1 and 2 the'character a indicates as an entirety thewalls of a cylindrical bin. The character a indicates hollow tile-blocks of ordinary construction, of which the walls of'the bin are built. The successive layers of tile-blocks are lapped and their horizontal surfaces are united by layers of mortar or cement b. Hitherto it has been found necessary to use some such material as wire-cloth to support the cement or mortar while in plastic, condition and to thereby prevent the same from fallinginto the cavities of the tileblocks. As this wire-cloth serves only the temporary purpose above indicated, its item of cost is one with which it is desirable to In accordance with my invention I wind the reinforcing-wire f,properl y spaced, in the form of a horizontally-disposed coil,

. over the faces of the upper layer of tile-blocks a, as indicated in Figs. 2 and 3.' For ordinary tile-blocks each coil of reinforcing-wire f is given about six convolutions. ThisI have found to be sutficient to support the body of mortar or cement I) while in plastic condition. The coilmay, however, be given a greater or less number of convolutions, if found expedient. Preferably the strands or convolutions of the coil f are properly spaced at suitable intervals bya transversely-woven wire-spacer g. However, in some instances temporary and removable spacers may be provided for holding the wire until the cementor mortar has been applied. When the cement or mortar is set,'t he coiled bindingwires f afford binding-bands which resist the lateral bulging strains put upon the bin-walls by the grain or other materials contained within the bin. Reinforcing-bands thus formed of wire are much stronger than metal bands of the same aggregate cross-section constructed in any other manner. It will The constructions illustrated in Figs. 4 and 5, while within the broad scope of my invention, are not the full equivalents of the construction illustrated in FigsJl to 3, inclusive, for the reason that the binding-wires in these latter constructions perform but a single function-to wit, that of reinforcements or binding-bands. In both of the constructions illustrated in Figs. 4 and 5 the bin-walls are shown as built of bricks it. In the construction illustrated in Fig. 4 the binding-wires f are coiled, as in the construction above described, and are embedded in the horizontal layers of mortar or cement b, while in the construction illustrated in Fig. 5 the binding-wires f are coiled vertically and embed% ed in vertically-extended layers of mortar From the foregoing description and statements made itwill be understood that my invention is capable of. considerable modifica tion other than that herein set forth.

From one point of view my invention consists in winding reinforcing-wires spirally in the cement which unitesthe blocks of the wall, regardless of whether or not the blocks are hollow. From another point of View my invention consists in placing the reinforcingwires,whether spirally'wound or not,between the horizontal rows of hollow tile blocks, whereby they are caused to serve as racks to support the cement while in plastic condition.

What I claim, and desire to secure by Let ters Patent of the United States, is as follows:

1. The combination with the walls of a bin or similar structure built of fireproof blocksunited by cement or mortar, of a bindingwire wound spirally and embedded in the ocment which unites the blocks, substantially as described.

2. The combination with the walls of abin or similar structure built of fireproof blocks united by cement or mortar, of reinforcingwires wound spirally in horizontal planes and embedded in the cement which unites the said blocks, substantially as described.

3. The combination with the walls of abin or similar structure, built of hollow tileblocks, arranged in layers united by cement or mortar, of closely spaced bindingwires laid between the layers of tile-blocks and embedded in the cement or mortar, which binding-wires overlie the openings in said tile-blocks and serve-to support the cement or mortar while the same is in plastic condition, substantially as described.

4. The combination with the walls of a bin or similar structure, built of hollow tileblocks united by horizontal layers of cement or mortar, of binding-wires coiled on horizontaleplanes and embedded in the cement which unites the horizontal'surfaces of the tile-blocks, substantially as described.

5. The combination with the walls of a bin or similar structure, built of hollow tileblocks ct, united attheir horizontal surfaces by-layers of cement or mortar b, of bindingwires f coiled in horizontal planes and embedded in the said layers of cement b, and spacing-wires 9 applied to the said wires f, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
